The Mavericks would need Shawn Marion to first sign his player option. The Cleveland Cavaliershave expressed interest in Marion and, having signed the veteran forward, could send some type of package (with or without picks) to the Celtics.

Trade future first-round picks.

The Mavericks still owe the Oklahoma City Thunder a future, protected first-round pick. With the Celtics rebuilding and looking for picks, proposing future first-rounders isn't in the mix.

Take on Brandon Bass and Courtney Lee.

If the Mavericks were to take on these contracts that the Celtics are looking to unload, then bringing in Dwight Howard might not be feasible.

This wouldn't make much sense for the Mavericks as they are trying to build around Nowitzki. Unless Mark Cuban has some crazy deal in place, there is virtually no chance of moving him. Cuban and the Mavericks are in search of another ring. It will definitely be an interested month of July all throughout the NBA.

What do you think the Mavericks should do for Rondo? Let me know in the comment section.
